I'm not really sure where to put this, but the homework section seems most appropriate, even though this pertains to research I'm doing, rather than homework.
I have 1.1 liters of saturated (31% by mass) calcium chloride solution which is sitting in a condenser so that it forms a cylinder that is 10 inches tall and has a radius of 1.5 inches (a surface area of 0.0699m2), and it's been chilled to -45 Celsius.
I'm trying to figure out how long it will take to get to 0 degrees with the room temperature at 27 degrees, but I'm really struggling. Pretty basic calculations will let you know that it's going to take around 150KJ, but I can't get past that.
Here are the other numbers that I know so far:
-the density of the solution is 1.31kg/L, which gives a mass of 1.441kg.
-the specific heat of saturated calcium chloride brine is 2600KJ/kg*K
I've been spending $300 a month on dry ice to cool this condenser, so I'm trying to come up with better ways of doing it. Any help is truly appreciated!
